The python script mkdocdeps.py is used to import the list of man pages
from the sphinx configuration to make.
This will delete the (release only) target update-man-versions. This
will be replaced in a followup commit.
This is the output from sphinx-quickstart, massaged a bit, along with
our existing man pages converted to rst.
A skeleton notmuch-emacs manual is also included. It is not suitable
for end user use yet.
